MEXICO CITY — The body of 36-year-old Hugo Hernandez was left on the streets of Los Mochis in seven pieces as a chilling threat to members of the Juarez drug cartel. A note read: "Happy New Year, because this will be your last."

To drive home the point, the assailants skinned Hernandez’s face and stitched it onto a soccer ball.

The gruesome find, confirmed Friday by Sinaloa state prosecutors, represents a new level of brutality in Mexico’s drug war, in which torture and beheadings are almost daily occurrences.

Hernandez was taken to Sinaloa after being kidnapped Jan. 2 in neighboring Sonora state, in an area known for marijuana growing, said Martin Robles, a spokesman for Sinaloa prosecutors. The motive for his abduction was unclear.

His torso was found in a plastic container in one location; elsewhere another box contained his arms, legs and skull, Robles said. Hernandez’s face, sewn onto a football, was left in a plastic bag near City Hall.
